Does anyone know where in the code this error is occurring at?

It runs fine locally when I am testing but once it is on the server it bombs and I get the error below. My system is:

• windows 2003
• exchange 2003 (5.5)
• .Net 1.1

Get the following error.

Server Error in '/netbranch' Application.

Hi Dauve,

The possible cause of this error is Smtp.Mail unable to locate your exchange server. Try checking the firewall for port 25 on which the Exchange server is configured.

Also, first try setting

SmtpMail.SmtpServer="localhost";

on the development (win2k3) machine. It should work. Check the "Queue" folder also to be sure that your application is working good.

Further, try specifying IP Address instead of name in SmtpServer property.

Lemme know if this works.

Take Care.

 Hi Irfan,

I am also getting the same error.

I tried with your solution by setting SmtpMail.SmtpServer = "localhost" but still it displays the same error.

My question is how to set the Port address in ASP.NET 1.1, I know about 2.0 & 3.5 but dont know about 1.1

Please give me some suggestions how to over come this issue....

Thanks

 

.Item(sch & "sendusing") = 2 ' cdoSendUsingPort

End With

'cdoMessage = CreateObject("CDO.Message")

End With

MyMail = Nothing

cdoConfig = Nothing

Finally I figured it out it is problem with our server settings .

The gateways are closed for the website in mail settings.

How did you resolve the problem? I do not know how to check is the gateways are close or not in mail settings.

Thanks

You need to verify with your Admin to make sure that the mail settings (gateways) are opened for ur website in the  server .

Thanks

HI drashti,

Please make sure your server IP address is added to the gateway or firewall. We had the same prblm and we contacted the admin he added our servers Ip address to the gateway. Then the mail sending option is good to go ....I thnk this is not the coding issue this is a permission issue.
